In the present work, porous Co₃O₄ was easily prepared via thermal decomposition of metal-organic frameworks (MOFs). TG, FT-IR, XRD, SEM, TEM and N₂ adsorption-desorption were employed for characterizing the synthesized products. Based on cataluminescence (CTL) transduction principle, three MOFs including dodecahedra ZIF-67, nanosheets packed Co-MOF-71, nanoplate Co-BTC, and their corresponding derivatives Co₃O₄ were used as sensing materials for H₂S detection, respectively. The dodecahedra ZIF-67-derived dodecahedra Co₃O₄ with high specific surface and exposed {110} lattice planes presented superior strong CTL property, and had a good linear relation in the concentration range of 3.3–27.5 μg L⁻¹ with the detection limit of 1 μg L⁻¹ (S/N = 3), while the original MOFs displayed no CTL signal. Eighteen common volatile organic compounds (VOCs) were investigated as possible interference, and the results indicated that MOFs-derived porous dodecahedra Co₃O₄ would be one of excellent sensing material candidates for monitoring H₂S with a promising application in routine analysis.

在目前的工作中，可以通过金属有机骨架（MOF）的热分解容易地制备多孔Co ₃ O ₄。用TG，FT-IR，XRD，SEM，TEM和N ₂吸附-脱附对合成产物进行表征。基于催化发光（CTL）转导原理，分别使用十二面体ZIF-67，纳米片状Co-MOF-71，纳米板Co-BTC及其相应的衍生物Co ₃ O ₄三种MOF作为H ₂ S检测的传感材料。。十二面体ZIF-67衍生的十二面体Co ₃ O ₄具有高比表面和暴露的{110}晶格面表现出优异的CTL性能，并且在3.3-27.5μgL ^-1的浓度范围内具有良好的线性关系，检测限为1μgL ^-1（S / N = 3），而原始MOF则没有显示CTL信号。研究了18种常见的挥发性有机化合物（VOC）作为可能的干扰物，结果表明，MOF衍生的多孔十二面体Co ₃ O ₄将成为监测H ₂ S的极佳传感材料之一，在常规分析中具有广阔的应用前景。
